Over-the-Air iOS 7.1 Download Files Deletable in Beta 3
Previously, updates downloaded over-the-air could not be removed, an issue that received attention in September after iOS 6 users were forced to install iOS 7 or lose 3.1 GB of storage space to the installation file.
Users with iOS 7.1 beta 3 who have not installed the update will see it listed in the Settings menu, under General --> Usage, where it can be removed like any other app or file. The file can be deleted if it was downloaded over-the-air in the background or manually.
While over-the-air files can be deleted as of iOS 7.1 beta 3, there is a possibility that this is a beta-only feature that will not make it into the final release of the software. Apple often adds and removes features during the course of beta testing, such as the dark keyboard that was available in iOS 7.1 beta 1 and removed in beta 2.
First released to developers last week, iOS 7.1 beta 3 also includes a number of visual changes that give iOS 7 a revamped look and feel, including a redesigned Phone dialer, an improved keyboard, and darker colors for the Phone, Messages, and FaceTime apps. It is unclear when Apple plans to release iOS 7.1 to the general public, but a December report suggested the update could launch in March after a lengthy beta testing period.
Update: As several commenters have pointed out, the new feature is actually part of the second beta, as it is the download for third beta that can be deleted without ever being installed.
